Ruth - Australia

"You watch the news with almost your bags half packed. You're ready to go at the drop of a hat."

From caring for malnourished kids in Sudan to treating the injured after typhoons and earthquakes in the Philippines and Haiti, Ruth has worked some tough gigs. “I've done 15 missions in the last 12 years,” says the nurse and aid worker.

“It's been hard, it's been tragic, it's been devastating and I feel like part of me is left behind every mission but at the same time that has enlarged the person that I am.”
